Description

Kühler für Luft- und Kraftfahrzeuge Die Erfindung betrifft insbesondere aus Leichtmetallelementen bestehende Kühler für Kraft- urid Luftfahrzeuge, deren Wandungsbleche durch ein aus ariderem Werkstoff bestehendes Verbindungsmittel zusammengefügt sind.Aircraft and Automotive Radiators The invention particularly relates Radiators consisting of light metal elements for motor vehicles, their Wall plates joined together by a connecting means made of a different material are.

Die Schwierigkeiten beim Aufbau von Kühlern, insbesondere aus Leichtmetallen, bestehen im wesentlichen in deT' geringen Korrosions- und Schwingungsfestigkeit der Verbindungen. Man hat deshalb derartige Kühler bereits so ausgeführt, daß man sie aus einzelnen voneinander unabhängigen Elementen aufbaute, inderü man diese durch Aufreihen auf Bolzen und Zusammenschrauben zu einer Einheit verbarid. Zur Abdichtung zwischen den einzelnen Elementen dienton Dichtungen aus elastischem Werkstoff, z. B. Gummi. _ Es ist weiter vorgeschlagen worden, derartiger Kühler als dünne Blechrahmen mit um diese Blechrahmen vulkanisierten Gummibekleidungen auszuführen, um derart das Einlegen besonderer Dichtungsteile zu ersparen. Solche Anordnungen führen indessen zu einer gewissen Sperrigkeit und bedingen weiter die Aufgabe eines ierheblidhen Vorteils des Leichtbaues, der im Verzicht auf ,alle nicht un.-mittelbar zum Kühler gehörenden und erforderlichen Bauteile besteht. Auch ist die Schwingungsfestigkeit derartiger Kühler nicht größer als die der üblichen, da sich !erfahrungsgemäß Schraubverbindungen unter dem Einfluß von Erschütterungen auf die Dauer lösen.The difficulties in building coolers, especially those made of light metals, consist essentially in deT 'low resistance to corrosion and vibration of connections. Such coolers have therefore already been designed in such a way that one built them up from individual, independent elements, in which they were built verbarid by lining up on bolts and screwing together to form a unit. To the Sealing between the individual elements is made of elastic material, z. B. rubber. _ It has also been proposed to use such a cooler as a thin sheet metal frame with rubber coverings vulcanized around this sheet metal frame, in order to do so to save the insertion of special sealing parts. Such orders lead, however to a certain bulkiness and further require the task of a hoist Advantage of the lightweight construction, which in doing without, all not directly to the radiator belonging and required components. Also is the vibration resistance Such a cooler is no bigger than the usual one, because experience shows that there are screw connections solve under the influence of vibrations in the long run.

Es ist nun vorgeschlagen worden, die -einzelnen Kühlerelemente durch Vergießen oder Tauchen mit Kunstharzschichten untereinander zu verbinden. Durch eine :derartige Verbindung .der Kühlerelemente untereinander @ergibt sich zwar eine sehr hohe Korrosionsbeständigkeit :der Verbindung, jedoch ist die Widerstandsfähigkeit gegen Schwingungsbeanspruchungen sehr gering. Verhältnismäßig bald ,auftretende Ermüdungserscheinungen zier Kunststoffverbindung lassen den Kühler bald undicht und unbrauchbar werden.It has now been proposed to use the individual radiator elements Potting or dipping with synthetic resin layers to connect with each other. By a: such a connection. of the cooler elements with each other @ results in a very high corrosion resistance: the connection, however, is the resistance very low against vibration loads. Relatively soon, occurring Signs of fatigue in the plastic connection will soon make the cooler leaky and become unusable.

Es ist weiter vorgeschlagen worden, Filterplatten aus mikroporösen Baustoffen dadurch untereinander zu verbinden, daß man sie ur;t(#r Wärmeeinwirkung mit mikroporösem Kautschuk verband.. Eine -solche Verbindung ist aber weder mechanisch ;ausreichend fest, um die bei Fahrzeugkühlern auftretenden Erschütterungen auszuhalten, noch ist sie absolut dicht, so daß sie für die Zwecke .eines Kühlers nicht brauchbar ist.It has also been proposed to connect filter plates made of microporous building materials to one another by connecting them to the action of heat with microporous rubber . Such a connection, however, is neither mechanical; sufficiently strong to withstand the vibrations that occur in vehicle radiators It is still absolutely tight, so that it cannot be used for the purposes of a cooler.

Die Erfindung hat den Aufbau eines Kühlers zum Zweck, welcher einen nicht nur korrosionsbeständigen, sondern auch schwingungsfesten Zusammenhalt der einzelnen Kühlerelemente untereinander besitzt.The invention has the construction of a cooler for the purpose, which one not only corrosion-resistant, but also vibration-resistant cohesion of the individual cooler elements among each other.

Die Erfindung besteht darin, da.ß als Verbindungsmittel zwischen den zu vereinigenden Teilen des Kühlers durch Haftung mit diesen Teilen verbundener Gummi dient. Ein geinäl.') der Erfindung hergestellter Kühler, bei dein Gummi das verbindende Mittel zwischen den einzelnen Bauteilen ist, ist in sich nicht absolut starr und infolgedessen der Gefahr einer Biz#-schädigung durch Schwingungen nicht mehr ausgesetzt.The invention consists in that as a connecting means between the parts of the cooler to be united by adhesion with them share connected rubber is used. A common cooler manufactured according to the invention, at your Rubber is the connecting means between the individual components, is not in itself absolutely rigid and, as a result, there is a risk of Biz # damage due to vibrations no longer exposed.

Eine besonders vorteilhafte Ausbildung eines Kühlers ergibt sich dann, wenn die einzelnen Kühlerelemente über Zwischenringe aus Gummi derart aneinander und gegebenenfalls an ein Sammelrohr angeschlossen sind, daß sie voneinander unabhängige schwingtiligsfähige Glieder bilden. _ Gemäß der Erfindung ist es somit möglich, einen .leichten Kühlei- zti bauen, welcher korrosions- und schwingungsbeständig ist und dessen Abmessungen und Gewicht die eins üblichen geschweilhen Kühlers nicht Übersteigen.A particularly advantageous design of a cooler then results when the individual cooler elements are attached to one another via intermediate rings made of rubber and are optionally connected to a manifold so that they are independent of one another Form limbs capable of swinging. _ According to the invention it is thus possible Build a .light-weight cooling system that is corrosion and vibration resistant and its dimensions and weight are not the same as those of the usual welded cooler Exceed.

Die Erfindung sei an Hand der beiliegenden Abbildungen dargestellt und erläutert. Die Abbildungen zeigen Abb. i die Verbindung zweier Kühlerbleche untereinander durch zwischen ihnen eingebrachten und festgehafteten Gummi, Abb. = die Anordnung mehrerer Kühlerelemente, wobei diese untereinander und mit einem Sammelrohr über zwischengelegte und mit den zu verbindenden Teilen festhaftend verbundene Ringe aus Gummi erfolgt.The invention is illustrated on the basis of the accompanying figures and explained. The figures show Fig. I the connection between two radiator plates among each other by means of rubber inserted and stuck between them, Fig. = the arrangement of several cooler elements, with each other and with one Collecting pipe via interposed and firmly connected to the parts to be connected Rings are made of rubber.

In Abb. i sind mit i und 2 zwei Kühlerbleche bezeichnet, welche miteinander zu verbinden sind. Diese Verbindung wird hergestellt durch einen Gummikörper 4., der gleichzeitig der Abdichtung dient und mit de:n Teilen i und 2 an den Flächen 3 und 5 festhaftend verbunden ist.In Fig. I, i and 2 denote two radiator plates, which are connected to one another are to be connected. This connection is made by a rubber body 4., which also serves as a seal and with de: n parts i and 2 on the surfaces 3 and 5 is firmly connected.

Die Zusammenschaltung und die Verbindung mehrerer Kühlerelemente mit einem Sammelrohr ist als Beispiel in der Abb.a dargestellt. Die aus den Seitenteilen i und bestehenden Kühlerelemente sind an ihren Enden untereinander, wie in Abb. i ersichtlich, und entsprechend Abb. a mit den dem Abschluß und dem Anschluß an das Sammelrohr dienenden Kopfstücken ff sclit%-ingungsdämpfend elastisch verbunden. Die Verbindung erfolgt mittels an ihnen festhaftenden Gummikörpern .l, welche gleichzeitig dein Anschluß der aus den Kopfstücken und den Seitenteilen bestehenden Kühlerelemente aii das Sammelrohr; dienen. Das Sammelrohr selbst dient gleichzeitig zur Aufnahme der Befestigungsmitte18, welche den Kühler im Rahmeng .aufzuhängen gestatten. Die Blech 11, 1_ stellen Zwischenbleche dar.The interconnection and connection of several cooler elements with a manifold is shown as an example in Fig.a. The ones from the side panels i and existing cooler elements are at their ends one below the other, as shown in Fig. i can be seen, and according to Fig. a with the termination and the connection to the header serving head pieces ff sclit% -singungsdämend elastically connected. The connection is made by means of rubber bodies adhering to them .l, which at the same time your connection of the radiator elements consisting of the head pieces and the side pieces aii the manifold; to serve. The manifold itself also serves as a receptacle the fastening means18, which allow the cooler to be suspended in the frame. the Sheet 11, 1_ represent intermediate sheets.

Die in den Abbildungen gezeigten Ausführungsformen sind als Beispiele zu werten. Die korrosionsbeständige. und schwingungsfeste Verbindung der einzelnen Bauteile des Kühlers untereinander kann an sich in beliebiger Weise dem jeweiligen @'erivendungszweck angepaßt «-erden.The embodiments shown in the figures are given as examples to evaluate.
